A lens for eyewear is configured to reduce the appearance of scratches on the lens and/or increase the durability of the lens. The lens can include a functional stack bonded to a lens body. The functional stack can include a functional layer, such as a thin film coating, sandwiched between the lens body and an optical-grade transparent film. The functional stack can increase abrasion resistance and environmental durability of the lens, and can reduce the appearance of scratches on the lens. The combined lens body and functional stack can increase the durability of the lens relative to a lens with a thin film coating (e.g., a gradient or mirror stack) on an external surface of the lens.

Provided is an optical film coating composition including: a UV curable acrylate resin; mixed particles including inorganic nanoparticles and carbon black; and a photoinitiator.

Provided is a conductive sheet including a transparent conductive layer and a brightness enhancement film, in which interlayer peeling hardly occurs. A conductive sheet of the present invention includes a brightness enhancement film, a resin layer, and a transparent conductive layer in the stated order. In one embodiment, the transparent conductive layer contains metal nanowires. In one embodiment, the metal nanowires include silver nanowires. In one embodiment, the transparent conductive layer further contains a binder resin.

The present invention pertains to a one-side-protected polarizing film having a transparent protective film on only one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin, has a thickness of 10 μm or less, and is designed to have a single-body transmittance T and a polarization degree P representing optical properties satisfying the condition of the following formula: P>−(10.sup.0.929T−42.4−1)×100 (provided that T<42.3) or P≧99.9 (provided that T≧42.3); and the other surface of the polarizer has a transparent resin layer having a thickness of 0.2 μm or more and formed from a layer-forming material including a polyvinyl alcohol-based resin. Even when the polarizer has prescribed optical properties and the thickness is 10 μm or less, this one-side-protected polarizing film is capable of suppressing the occurrence of through cracks and nano-slits.

The present invention provides an optical film including a light reflection layer, in which the light reflection layer is a layer in which alignment of liquid crystal molecules is immobilized, the liquid crystal molecule forms a helical structure in a film thickness direction of the light reflection layer, and a tilt angle of the liquid crystal molecule is 15° to 55°. The present invention also provides a manufacturing method of the optical film including curing a polymerizable liquid crystal composition including a liquid crystal compound and a chiral agent interposed between a support and another support. In the optical film according to the present invention, an absolute value of oblique retardation is smaller. In the liquid crystal display device including the optical film, front surface brightness is high and an oblique change in the shade is suppressed.

A method for producing a polarizing film includes (1) preparing a laminate (a) which includes a carrier film and a polarizer with a thickness of 10 μm or less formed on one surface of the carrier film and contains a polyvinyl alcohol-based resin; (2) peeling off the carrier film from the laminate (a); and (3) applying a liquid material to a side of the laminate (a) from which the carrier film has been peeled off and then solidifying or curing the liquid material to form a transparent resin layer with a thickness of 0.2 μm or more, wherein the liquid material contains a resin component or a curable component capable of forming a resin layer. This production method enables the achievement of a polarizing film which is able to have satisfactory durability in a heated environment even in cases where a thin polarizer is used therefor.

The present invention pertains to a one-side-protected polarizing film having a protective film or films on only one surface of a polarizer, wherein: the polarizer contains a polyvinyl alcohol-based resin, and is designed to have a single-body transmittance T and a polarization degree P representing optical properties satisfying the condition of the following formula: P>−(10.sup.0.99T−42.4−1)×100 (provided that T<42.3) or P≧99.9 (provided that T≧42.3), and the polarizer and a transparent resin layer have a thickness X (μm) and a thickness Y (μm), respectively, satisfying X≦12, Y≦15, and 0.15≦(Y/X)≦3. Even when the thin-type polarizer has prescribed optical properties, this one-side-protected polarizing film is capable of suppressing the occurrence of through cracks, nano-slit-induced defects and curling.

A laminated film includes a plurality of optically anisotropic layers, excellent in transparency, with few point defects, and exhibits little reflected light where the laminated film is applied to a display device brought into a black display state; and a circularly polarizing plate. The laminated film includes first, second, third, and fourth optically anisotropic layers, in order, in which the first, second, third, and fourth optically anisotropic layers are each formed by fixing an aligned liquid crystal compound, an adhesion layer selected from the group consisting of an adhesive layer, and a pressure sensitive adhesive layer is provided on only one of between the first and second optically anisotropic layers, between the second and third optically anisotropic layers, and between the third and fourth optically anisotropic layers, and the laminated film has a minimum transmittance of 60% or more in a wavelength range of 400 to 700 nm.

The present invention provides a barrier film laminate including a first barrier film that includes a first substrate layer and a first barrier layer formed on the first substrate layer, a second barrier film that includes a second substrate layer and a second barrier layer formed on the substrate layer, and an adhesive layer. In the barrier film laminate, the first barrier film is bonded with the second barrier film so that the first barrier layer faces the second barrier layer with the adhesive layer interposed therebetween. In one embodiment of the barrier film laminate, the adhesive layer is formed of an adhesive containing an epoxy resin, a curing agent having an amino group, and either a silane coupling agent having an epoxy group or a silane coupling agent having an amino group and two hydrolyzable functional groups.

The object of this invention is to provide a laminated automotive glazing having an obscuration area produced by printing the obscuration on a film laminated between at least two layers of plastic interlayers or directly on the interlayer rather than printing and firing an enamel frit onto the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration.
